H.R. 1651 would overturn an Environmental Protection Agency rule issued in May 2024 that sets greenhouse gas emission limits for coal and gas-fired power plants, both new facilities and existing ones already in operation. The bill would eliminate the EPA's standards that require power plants to reduce their carbon dioxide emissions, effectively canceling the regulation that also repealed a previous Trump-era rule called the Affordable Clean Energy Rule. The legislation would affect power generation companies and their operations across the country, though it contains no specific funding provisions or implementation timeline beyond nullifying the rule. The bill was introduced by a group of House Republicans and referred to the Committee on Energy and Commerce.
